Please consider this strange behavour: I have an outer and an inner loop. I want to stop (= break) the Inner loop on an condition. But this the loop behaves different when I test for i and in the Second programm for j in the condition. WHY? What I want is the result of programm „Test61“: The inner loop Should end when j is a 1. But why that behavour in „Test61a“? Thanks for your answers.
